Question

119. The variation of velocity of a particle with time moving
along a straight line is illustrated in the following figure
The distance traveled by the particle in 4 s

(1) 60 m (2) 55 n ) 25 m (4) 30 m​

Answer 1

Answer:

(2)55 m

Explanation:

the area of the covered area is the displacement of the particle.

so,the displacement=1/2×1×20+1×20+15+1×10=55 m
